TO ALL WHOMlT MAY CONCERN:

Be it known thot I, GEORGE CnoMPToN, of Worcester, in the-` county of Worcester, and State of Massachusetts, have invented Improvements in Looms; and I do hereby declare that the following, token in connection with the drawings which accompany' und form part of this specification, is o. description ofimy invention, sucient toennhle those skilled in the ort toproctisc it;

The invention relates principally to the construction und arrangement of the harness f'mechanism of fancy looms, and more particularly to'the relative.arrangement of the eveners, lifters, and jdepressers for working the heddlelevers. l

The drawings represent as much of the z nechunism of o loom embodying my'invention as i's necessary to u. cle-nr und full understanding of the inventioni y Figure 1 showing nn end view, and

Figure 2 n. side elevation of the same.

a denotes the frame; I) I) thehnrness-lenves' attached to the inner ends of the pairs of heddlc-levers c, whose outer ends nre connected by the vertical jncks d und the Iconnecting-wires e. The hooks upon these jeclcs are carried into connection with the respective lifter and depresser bnrsfg by the pattern-cylinder 7L in the ordinary' manner, ench being lifted or depressed to reise or lower the particular harness-frame connected to it, accordingly us itinn-ybe carried into connection with either the lifter or the depre'sserl bor bythe action ofthe pattern- Cylinder; und the several hooks are all brought int-o line after each change by one or two pairs of eveners n. The lifter-s :1nd dcpressers are worked fronr the shaft Zby cranks m n and oonnectiug-rods op, and they are arranged os levers to work upon adjustable'fulcrol q, secured in slots r in o stationery bracket or plate', s, projecting from thc frame' 1,'the fulcro. .being arranged in 'or nearly in the some vertical plane with thev line in which the cloth isl runde und the weft bouten up, this arrangement for working the` lifter end depresser levers froin'these points effecting n uniformity or uniform inclination in the shed through all the harness-levers. l

Such en arrangement is not new in itself, but in order to give'a.- precisely corresponding movement to the eveners v, Ihong each one of these upon mi adjustable fulcrum, t, in vertical line with the respective lifter or depresser with which it is connected, and by which it is worked, (through the link en) the respective eveners being thereby'kept porullel with their respective lifters o r depressers, and thereby exerting en equal stress upon .all the heddle-levers together, all the hooks bearing with equal force upon the lifter or depresser with which they' may beengnged.

Another port of the invention relates to o; simple menus of disengagmg the cloth-roll from the gen1-ing, through which movement is imparted to it to wind the cloth, this disengagement being desirable whenever the Vcloth is to be run oil' from the rolls, so that the roll may run free from any friction other thanthat vof its journals in their bearings.

The improvement consistsin mounting the journal oltthegeored end Aof the roll in n movable beeringprovided with rneuns for locking it in gear with the pinion which drives 'it when the loom is in operation, and for locking it out of geur .when the cloth is to be run oiffrom the roll. v

a denotes the cloth-roll, carrying a gear, In', driven by o pinion, c', und ratchet-geur, d', in the ordinary manner. The journolof the roll adjacent to the gear is mounted on a. movoblebearing, e', sliding in a. box,f, this bearing having two holes, g, for-receiving o. locking-pin, t", the box f being open :ttv one side, V:ts seen et k', and beingslotted :it its inner'side to allowv movement of the journal. When the rollsgenr is inA connection with the pinion e it is heldin such connection by inserting the pin t" in the upper hole g', thereby locking the .bearing from ascent. When the cloth is to be run oh", the-piu is withdrawn, the geared end of the roll is raised, `carryingwith it the bearing e, which is` then4 locked in this rsised'postionv by inserting the pin in the lower hole gf, thegeors beingnow out' of connection.

I claim, in combination with the li'ftei-ztnd depresser levers, hung upon Iulcra. in line with; the cloth-making point, as described, the evener levers, Aconnected to and'actuotedby the'lifter and depresser levers, when the eveners are hung upon fulcro in line with the fulerum of the respective lifteror depresser to which each is conneeted,`substontinlly as set forth. i

Also, in eombinntion'with the'lmcchanisin of a loom, a. cloth-roll, heving'uprovision'for locking it 'either in connection or out of connection with vthe mechanism through which it is driven, substantially os set forth.
